Regarding whether a person will breathe after inhalation anesthesia, it first depends on which kind of breathing, which is generally considered by internet users as autonomous breathing, that is, in the daily state. There is another kind of breathing that is passive assisted breathing or mechanical ventilation, which is assisted by artificial means or assisted by ventilator. It is possible to preserve voluntary breathing with inhalation anesthesia, but this is a relatively rare occurrence. It is not a question of whether anesthesia itself can preserve voluntary breathing, because no one would do anesthesia without disease; anesthesia is usually done to complete an examination or surgery. That is, the implementation of anesthesia is related to at least three aspects, as follows: 1. the patient’s own state: whether he or she is old and frail, whether there are diseases other than surgical diseases; 2. the need for surgery: surgery is for treatment, so if autonomic breathing will interfere with the operation, or if preserving autonomic breathing will make the operation more traumatic, do not preserve autonomic breathing; 3. the experience of the doctor who performs the anesthesia: when preserving autonomic breathing The anesthesiologist needs to observe the patency of the airway and adjust the dosage precisely according to the intensity of the surgical stimulation, as well as to observe other vital signs, which is somewhat difficult.
